Checking the cooling system
● With the machine stopped, check the condition of the cooling system:
– The cooling system is in good condition.
– The pressure drop between entry and exit has not increased appreciably.
9.1.6 Servicing and maintaining the anti-condensation heating
The anti-condensation heating is maintenance-free. If it is defective, contact the Service Center
(Page 163).
9.1.7 Assessing the roller bearings
To assess the roller bearings, it is generally not necessary to dismantle the machines. The
motor only has to be dismantled if the bearings are to be replaced.
The state of a roller bearing can be assessed by analyzing the bearing vibration. The measured
values provide an indication and can be assessed by specialists. Contact the Service Center.
9.1.8 Roller bearings with automatic regreasing system
The roller bearings are supplied with new grease by the regreasing system.
● Replace the grease cartridge timely.
● Observe the operating instructions for the regreasing system when replacing the grease
cartridges.

● Only use the grease that is specified on the lubricant plate.
9.1.9 Regreasing intervals and types of grease for operating roller bearings
The specified grease data applies to the data specified on the rating plate and for high-quality
grease in accordance with the specifications in these operating instructions. Because these
greases exceed significantly the requirements according to DIN 51825 and ISO 6743‑9, they
permit the specified relubrication intervals.
Initial lubrication
The grease specified on the lubricant plate is selected according to the operating conditions
known at the time of ordering and should be used for initial lubrication.
